Public Member Functions
	IFSelect_SelectRoots ()
	Creates a SelectRoots.
Interface_EntityIterator	RootResult (const Interface_Graph &G) const override
	Returns the list of local roots. It is redefined for a purpose of efficiency: calling a Sort routine for each Entity would cost more resources than to work in once using a Map RootResult takes in account the Direct status.
bool	Sort (const int rank, const occ::handle< Standard_Transient > &ent, const occ::handle< Interface_InterfaceModel > &model) const override
	Returns always True, because RootResult has done work.
TCollection_AsciiString	ExtractLabel () const override
	Returns a text defining the criterium : "Local Root Entities".
Public Member Functions inherited from IFSelect_SelectExtract
bool	IsDirect () const
	Returns True if Sort criterium is Direct, False if Reverse.
void	SetDirect (const bool direct)
	Sets Sort criterium sense to a new value (True : Direct , False : Reverse).
virtual bool	SortInGraph (const int rank, const occ::handle< Standard_Transient > &ent, const Interface_Graph &G) const
	Works as Sort but works on the Graph Default directly calls Sort, but it can be redefined If SortInGraph is redefined, Sort should be defined even if not called (to avoid deferred methods in a final class).
TCollection_AsciiString	Label () const override
	Returns a text saying "Picked" or "Removed", plus the specific criterium returned by ExtractLabel (see below).
Public Member Functions inherited from IFSelect_SelectDeduct
void	SetInput (const occ::handle< IFSelect_Selection > &sel)
	Defines or Changes the Input Selection.
occ::handle< IFSelect_Selection >	Input () const
	Returns the Input Selection.
bool	HasInput () const
	Returns True if the Input Selection is defined, False else.
bool	HasAlternate () const
	Tells if an Alternate List has been set, i.e. : the Alternate Definition is present and set.
occ::handle< IFSelect_SelectPointed > &	Alternate ()
	Returns the Alternate Definition It is returned modifiable, hence an already defined SelectPointed can be used But if it was not yet defined, it is created the first time.
Interface_EntityIterator	InputResult (const Interface_Graph &G) const
	Returns the Result determined by Input Selection, as Unique if Input Selection is not defined, returns an empty list.
void	FillIterator (IFSelect_SelectionIterator &iter) const override
	Puts in an Iterator the Selections from which "me" depends This list contains one Selection : the InputSelection.
Public Member Functions inherited from IFSelect_Selection
Interface_EntityIterator	UniqueResult (const Interface_Graph &G) const
	Returns the list of selected entities, each of them being unique. Default definition works from RootResult. According HasUniqueResult, UniqueResult returns directly RootResult, or build a Unique Result from it with a Graph.
virtual Interface_EntityIterator	CompleteResult (const Interface_Graph &G) const
	Returns the list of entities involved by a Selection, i.e. UniqueResult plus the shared entities (directly or not).
Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.
	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.
Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.
virtual	~Standard_Transient ()=default
	Destructor must be virtual.
virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.
bool	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.
bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.
bool	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
bool	IsKind (const char *const theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
int	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
virtual void	Delete () const
	Memory deallocator for transient classes.

Protected Member Functions
bool	HasUniqueResult () const override
	Returns True, because RootResult assures uniqueness.
Protected Member Functions inherited from IFSelect_SelectExtract
	IFSelect_SelectExtract ()
	Initializes a SelectExtract : enforces the sort to be Direct.

Additional Inherited Members
typedef void	base_type
	Returns a type descriptor about this object.
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.
static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.

Detailed Description

A SelectRoots sorts the Entities which are local roots of a set of Entities (not shared by other Entities inside this set, even if they are shared by other Entities outside it).
